If the universe is a black hole and all matter, mass and energy are part of a black hole than there is no mater, mass or energy that exists outside itself. Thus, there exists nothing outside the universe on which the black hole universe can have a gravitational effect and in this case the black hole universe has no external gravitation. I am not quite sure if this is what you mean?Yours Cosvis. |
My understanding of this is that black-holes, just as you have stated, at the event horizon, and from the event horizon in, would pull all light, headed out, back into their centers, thus I can only see them, also, pulling all gravity, and most all em waves, back into their centers, from the edge of the event horizon, only___No external gravity. Of course, this is still just theory, but if the theories hold, then black-holes can have no external gravity, just internal gravity. Doesn't that make theoretical sense...? Of course, I do accept the theoretical observations of recent x-ray sattelites, showing radiation plumes exiting the conjectured black-holes, at the center of galaxies... At least, it allows theoretical physics and cosmology to possibly make advances___No...?
I don't see as this is in any dis-agreement, with what you generally stated... When we are talking about both the infinite universal black-hole, and the possible black-holes, existing within the universal black-hole, the theorizing gets a bit mis-construed, but I think our thinking is on the proper theoretical track___No...? For all I know, the infinite universal black-hole, may be made up of trillions, to the trillions, of
evolving/growing micro-infintesimal finite black-holes, within the greater infinite universal black-hole, and
some coalescing into the galaxies, we see... It's just a theoretical idea... Of course, this would raise the question of, "Can the fundamental infinite infintesimal substance parts, form into micro black-holes, and how...?" And possibly, "What would be the required cosmological geometry of such a fundamental wave/substance field...?"
